Random Subsector Generator

1001 SubSectors – Create Random Traveller SubSector Maps!

Select the race You want Your subsector generated for. The rules for subsectors are a bit different depending on which race You select. The planet names will be in a common language use by that race. If You select a frontier, outer limit or barren settlement type, then the planets are not part of the standard empire for that race. For Vargr, only small empires exists, so this is what will be created. If You select Pocket-Empires, You will (usually) get two interstellar powers in the same subsector (just as I recommend if You want to create a popular subsector.) If you select Zork, you will get a subsector with planet names that are inspired by an intrepid space explorer in a very small ship (that usually crashes.)

Select which subsector of the sector You want to create. This will only affect the numbering of the planets.

Select what type of settlement this subsector will have. This will affect the starport quality, the population, and the tech-level. Zhodani is limited to tech-level 14 unless the settlement is Hub or Capital. The settlement value also restricts the population modifier for population-A worlds. It also affects the alignment code, especially for the Vargr race, and it also affects the name of the subsector and sector.

Sector name:
Select if You want a random name for the sector, or if You want to determine the name yourself.

Subsector name:
Select if You want a random name for the subsector, or if You want to determine the name yourself.

Capital name:
Select if You want a random name for the subsector capital, or if You want to determine the name yourself.

Select the stellar density for the subsector. Standard is 50% chance for each hex having a system. Look at the classic rule books for more info.

Output style:
If You select Java, the map will be presented with Jo Grant’s very nice java viewer. If You select ascII, the map will be made with ascII characters. For ascII You can select a white background, to make printing easier.

Send to TravellerMap.com:
Select your options for the map style and click “Send to TravellerMap.com” to send the random data to Traveller Map. The generated map opens in a new window.

Hydrographics is calculated differently using different Traveller rule versions.

Four versions (Book-3, T4, T20, T5) use:
Hydrographics = 2d-7+atmosphere

Four versions (Book-6, MT, TNE, MgT) use:
Hydrographics = 2d-7+world size.

Atmosphere Fix:
If you select “NO”, then standard rules are used for atmosphere. If you select “YES” then my house rule for atmosphere and size is used.

  1. Nice setup but… I can’t seem to save the whole map. Only the wall of text at the left side is selectable but the map can’t be completely selected. If it was a picture I could save it, if it had a scroll feature I could view it all and save it (by screen shot if nothing else)

  2. I don’t know why you cannot select the ascii map. (I can select it.)

    But to get a better map, you can use the “send to TravellerMap.com” function.

  3. Love the Settlement option. I am working a small spreadsheet project to do the same thing, do you have any guidelines for how the Barren through Capital levels specifically affect the UPPs? Thanks for any help.

  4. Is there an option to manually adjust some settings in the UPP? Or remove some caps (I was trying to create a Darrian Pocket-Empire but TL seems to be capped).

  5. What do the Barren, Outer Limit, Frontier, Backwater, Standard, Mature, Hub, and Capital Settlement options actually do? Is this from a published article somewhere or something of your own creation?

  6. The Settlement is my own creation. It changes the flat probability for a dice. No illegal values will be created.

    Frontier to Barren will also place the worlds outside the Imperium. (Except for Vargr and Pocket-Empire where only Barren is outside.)

  7. Can someone please link me to somewhere I can have the actual meanings of the Remarks? I mean. WTF is Lo???
